"I like singing in Hindi/Punjabi, playing my guitar, and all things Bollywood. With my YouTube videos, it's a fun way for me to connect with other people who like Bollywood," Lev told Digital Spy.

"I've covered all of the Jab Tak Hai Jaan songs except 'Jiya Re', and only because I can't figure out the chords."

Lev's guitar interpretations of AR Rahman's music have been described as acoustic stripped-back versions of the original.

"I play at this speed, as that's the tempo that seems to come most naturally to me when I play the guitar, it feels fun to play that way," he added.

Ashanti Omkar, who is Bollywood Editor for Cineworld Cinemas, said of the singer: "I came across Ris when he used to work at The O2 and he was always keen to discuss the newest Bollywood releases. I was taken aback at how he enunciated the words, and how he delivered the songs in his own inimitable style.

"He made Bollywood his own. Upon digging deeper, he told me about how he was British African and Russian - a very unusual mix.

"I'm so proud to see how Bollywood in cineplexes has allowed it to reach so deeply - beyond Asian audiences in the UK - and has touched the likes of Ris."
